I BED-SPRING.

T0 all whom it may concern Be it known that I, EDGAR S. JorrNs'roN, a citizen of the United States, res1d1ng at Munson Station, in the county of Clearfield and State of Pennsylvania, have invented certain new and useful Improvements in Bed-Springs of which the following is a specification.

' This invention relates to the subject of beds and more particularly to the manner of constructing the springs for the bed such that they may be readily folded into a compact form in order that they may be earned more easily and occupy less space when being transported.

The primary object of the invention is to construct a bed spring which is adapted to be collapsible and at the'same time possess the necessary resiliency along theiadjacent 2O 'tinued use without discomfort to the occufolding edges, such'as to permit its conpant ofthe bed; 7

Another object of the device is to provide means for supporting the springs which carry the joint between thetwo sections in such manner thatone section is readily revoluble upon the other section.

A still further object of the device is to provide means for constructing the sections such that they are not easily distorted and pushed out of shape when being handled or shipped in express cars. a

With these and many other objects in view which will become more readily apparent as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts as will be hereinafter fully pointed out, illustrated and claimed.

It will be quite readily understood by those skilled in the art to which this invention belongs, that changes in details of construction may be resorted to without departing from the spirit or scope of the invention, but a preferred and practical embodiment of the invention is shown in the accompanying drawings in which Figure 1 is a plan view of my improved bed spring, the same being unfolded.

Fig. 2 is a side elevation of the unfolded bed spring shown in Fig. 1.

Fig. 3 shows a view of my improved bed spring as it would appear when folded into a compact shape for handling.

Fig. 4 shows the manner of supporting the springs on the spring channel which is Specification of Letters Patent.

designed .to engage the rail at the side of the bed. 7

Fig. 5 is .a detail sectional VlGW illustrating more clearly how the springs are mounted. a

Fig. 6 is a vertical section taken on the line 6 6 of Fig. 5 lying in the direction of the arrows.

In carrying out the invention no change is contemplated in the usual construction of the bed, nor in the general design of the individual springs, but there is contemplated a collapsible bed spring designated in its entirety by the numeral 10, having sections 11 and 12, the section 11 being susceptible of being revolved and superposed upon the section 12, as shown in Fig. drawings.

One common fault of springs ofthis type is to be found in the insuflicient support given the adjacent edges of the sections, and in order to overcome the fault I have constructed this device such that the adjacent edges are firmly supported upon a series of springs A as illustrated in Fig. 1, while one section is adapted to carry with it the springs S whenin its collapsible positions as shown in Fig. 3 of thedrawings.

That is to say, one of the important fea tures of the present invention is to provide a spring consisting of framed sections foldably connected at their upper adjacent edges,

3 of the and a series of springs affording a common support to the adjacent edges of said sections, whereby when the two sections of the spring are disposed in the same plane, the connected edges thereof will have the same support as the rest of the spring.

Referring now to the construction of the sections 11 and 12 it may be noted that each of the same consists of a plurality of supporting bars 13 whose end portions 13 are turned upwardly to thus provide a supporting bar of substantially U-shaped formation which constitutes the lower abutment for the springs S. Theupper ends of the up-turned portions 13 of the bar 13 have secured thereto a horizontal frame member 14 which serves to space the bars 13in parallel relation longitudinally of each section, and at the same time provides a rigid supporting base for all of the springs. As will be observed from Figs. 2, 3 and 4:, the'upper extremities of the upwardly projecting portions 13 of the bars 13 are provided with the bed rail engaging stirrups 17, so that when the sections are disposed in the same horizontal plane the combined frame-work 13-14 may be supported by the rails at the side of the bed.

In connection with the springs S it may be noted that the lower ends thereof rest upon the upper edges of the bars 13, and are held in position by means of the tie-wires 15 which cross the bars 13 at right angles and pass over the lower coil of the springs and through the openings 15 in the webs of the bars 13 as shown in Fig. 6, and. thence over the opposite side of the said lower coil spring to prevent the displacement of the latter from the upper edge of the bar. The upper ends of said springs are engaged by the crossed tie-wires 19 which extend at right angles to each other transversely and longitudinally of the spring and are securely fastened to the rectangular frame 20 which constitutes the upper frame element of each frame section. Thus, it will be clear that the springs S are confined between the crossed tie-wires 19 which constitute an upper spring abutment and the bars 13 which constitute a lower spring abutment.

From the foregoing it will be apparent that each of the sections 11 and 12 includes a plurality of arallel bars arranged and held in spaced pa 'allel relation, longitudinally of the sections by means of the rectangular frame member 14, while the springs S are supported on the upper edges of the bars 13 and held in position by means of the tie-wires 15 as suggested in Figs. 5 and 6 while the upper ends of the said springs S abut against the crossing points of the tiewires 19 which are stretched at right angles to each other from side to side and end to end of the rectangular frame member 20 at the upper edge of each section. And, for the purpose of uniting the two sections so that the one may be rotated upon the other the adjacent sides of the frames 20 are connected by the coupling rings 21 as clearly shown in Figs. 1 :2 and 3 of the drawings, and as also shown in Fig. 3, the series of springs S adjacent the edge of the section 11 is set beyond the plane of this edge of the section so that when it is rotated out into the same plane as the section 12 this series of springs will serve to support the adjacentcdge of the frame 20 as shown in Figs. 1 and 2.

I claim 1. In combination with a bed-spring comprising framed sections foldably connected at their upper adjacent edges, supporting springs in each section, and a series of springs affording a common support to the said adjacent edges and connected to but one of them.

A bed spring comprising hingedly connected sections foldable one upon the other, and each including a frame carrying a plurality of coil springs, one of said sections carrying a series of springs along its hinged edge, said series of springs being so arranged as to span the hinged joint between the spring sections when the latter are opened to form a full width bed spring.

In testimony whereofv I aflix my signature in presence of two witnesses.
